Why GCC toolchain

  • 100% opensource and free
  • Controll everything of CoreSTM32
  • Discover 100% power of STM32 micro processor. Much higher performance compared to Maple IDE.

Setting up GCC toolchain

You have two choices:

OR


It is said that Sourcery CodeBench Lite has better performance than other versions of compiler, but we haven't made any test.

Using IDE(Integrated Development Environment)

I prefer Eclipse, but you have multiple choices, like

Testing Program: Blink

#include "stm32f10x.h"
#include "stm32f10x_gpio.h"
#include "stm32f10x_rcc.h"

int main(void) {

  int i;
  GPIO_InitTypeDef GPIO_InitStructure;
  RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA, ENABLE);
  GPIO_InitStructure.GPIO_Pin = GPIO_Pin_8;

  GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP;
  GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
  GPIO_Init(GPIOA, &GPIO_InitStructure);

  while (1) {

    GPIO_SetBits(GPIOA, GPIO_Pin_8);

    /* delay */
    for (i = 0; i < 0x1000000; i++)
      ;
    GPIO_ResetBits(GPIOA, GPIO_Pin_8);

    /* delay */
    for (i = 0; i < 0x1000000; i++)
      ;
  }
}
